Your Zodiac Sign Is 2,000 Years Out of Date

Whether you care about horoscopes or not, you probably know your zodiac sign. You’ve probably known it for most of your life.

Zodiac signs were originally based on the stars. But over thousands of years, our view of the stars has shifted. That means, if you account for this shift, your sign might not be what you think.

Below, we’ll tell you what it would be instead.

There are three reasons the zodiac signs no longer line up with the constellations they’re named after.

1. Earth’s wobble

The Earth wobbles like a top. A spinning top starts to wobble soon after it is set into motion. The Earth does the same thing, only more slowly.

It takes 26,000 years for the North pole to trace out a complete circle in the sky, pointing at different stars along the way. Scientists call this wobbling motion axial precession.

This wobble means that our view of the stars shifts by one degree every 72 years. Over centuries, this difference builds up.

And it’s not just the Northern stars that shift in our view because of Earth’s wobble, but all stars — including the zodiac constellations.

Take the spring equinox, usually around March 20, the first day of spring in the Northern hemisphere (and the start of the zodiac calendar in Western astrology).

This shift in our view of the stars was discovered by Hipparchus over 2,000 years ago. Since you can’t see stars during the day, he waited for a lunar eclipse — when the moon is directly opposite the sun — and used the moon’s position to work out where the sun was.

By comparing his measurement with earlier ones, he found that our view of the stars shifts by about one degree per century — not too far from modern measurements.

Today, Western astrology uses the tropical zodiac system, which is based on the positions of the stars more or less as they would have appeared to Hipparchus, and not as they appear today.

That means that the zodiac signs familiar to Americans are in sync not with the stars, but with the seasons: Aries starts on the first day of spring, even though the sun is now in front of Pisces then.

In contrast, the Indian system of astrology uses the sidereal zodiac, which accounts for Earth’s wobble and aligns zodiac signs to the stars.

While these two systems were initially aligned, they have been drifting apart ever since. Western astrologers are well aware of this mismatch, but they don’t see a problem with basing the signs on the stars as they were two millennia ago.

“Astrologers using the tropical zodiac are just using what they consider to be an equally valid system,” said Dorian Greenbaum, a historian of astrology who teaches at the University of Wales Trinity Saint David.

2. Constellations differ in size

The zodiac signs were created around 2,500 years ago by the Babylonians.

Their star catalogs listed at least 17 zodiac constellations. But they eventually simplified these into the 12 zodiac constellations we know today, each 30 degrees wide, as if slicing the sky into 12 equal slices.

But constellations aren’t really the same size. In 1928, astronomers divided the sky into 88 officially recognized constellations, each one shaped like its own puzzle piece.

Official constellations along the sun’s annual path

“They are not nice equal pieces,” said Stacy Palen, emeritus professor at Weber State University. “They’re like jagged shapes that are not symmetric in any way.”

Based on these boundaries, the sun spends more than twice as much time in front of Virgo as in front of Cancer. And it spends only a week in front of Scorpio — if you include Ophiuchus, that is.

Which brings us to the last reason the 12 signs don’t align with the zodiac constellations.

3. Ophiuchus

Ophiuchus is the 13th constellation along the sun’s path, according to astronomers. (It even has its own emoji: ⛎.) Ophiuchus means “serpent bearer” in Ancient Greek, and is usually depicted as a man holding a snake. If you squint, you can kind of see why.

So for people born during the sign of Scorpio 2,000 years ago, Ophiuchus was more likely behind the sun on their birthday. (And because of Earth’s wobble, most Sagittarians today were also born when Ophiuchus was behind the sun.)

We don’t really know why the Babylonians left out Ophiuchus from their zodiac signs. They may have originally had a different name for it. But historians believe that when Babylonians simplified their zodiac system, they wanted the 12 zodiac signs to match the 12 months of their calendar. Ophiuchus didn’t make the cut.

A ‘shape-shifter’

Astronomy and astrology have little in common today, and there’s no scientific basis to the idea that the movements of the stars and planets influence our future or our personalities. But the two disciplines started out as the same thing thousands of years ago.

“If you were an astronomer, you were also an astrologer,” Professor Greenbaum said.

The Babylonians viewed the planets as gods, and planetary motions as omens that could foretell the fortunes of kings and kingdoms. This motivated them to look for patterns in the sky.

Even by the 17th century, many astronomers were also practising astrologers. Johannes Kepler, who discovered how planets move in ellipses, probably learned astrology at college, and created horoscopes for friends and patrons. Galileo practiced astrology and sold horoscopes on the side.

“Their side hustle was to cast horoscopes for their rich patrons because that paid the bills,” said Tyler Nordgren, an astronomer and author.

Eventually, during the Enlightenment, astrology was divorced from astronomy and was no longer considered a legitimate science, Professor Greenbaum said.

“It was kicked out of the universities,” he said. “But there were still practitioners.”

Today, we understand the laws governing the motions of planets and stars well enough to send spacecraft to distant worlds, detect gravitational waves and take pictures of a black hole. At the same time, over a quarter of Americans believe that the positions of the stars and planets can affect their lives.

So why has belief in astrology endured, while other methods of divination like ornithomancy (finding omens in the behavior of birds) or tyromancy (fortune telling with a block of cheese) have drifted into obscurity?

“Astrology is a shape-shifter,” Professor Greenbaum said. “Astrology goes along with whatever’s in vogue and manages to survive.”

Because those constellations are behind the sun, they’re in the daytime sky, and so you can’t actually see them on those dates. You’ll need to wait until they’re in the night sky, about six months from the date you entered.

How we found your sign

Advertisement

Though the astrological zodiac calendar is well known, there are small ways ours may differ from other sources. To calculate your astrological zodiac sign, we divided the sun’s annual path across the sky (known as the ecliptic) into 12 equal divisions of 30 degrees, beginning with the March equinox, which marks the beginning of Aries. This is the tropical zodiac system, in which zodiac signs are aligned to the seasons.

To calculate the astronomical zodiac constellation behind the sun, we used the Astronomy Engine software library to locate the sun on every day of the year and determine the astronomical constellation behind it.

We based our zodiac calculations on the current year, and on the position of the sun at noon UTC every day. A more accurate calculation of your sign would involve knowing the exact time and year of your birth, and as a result our calculations may be off by a day or so. This primarily affects people whose birthdays are on the cusp between two signs, or between two constellations.

To create the 3D illustrations of the stars, we used a repository of celestial data for the 88 official constellations, and oriented these constellations based on Earth’s view of the stars on a given date.

The astronomical calculations account for precession (the slow wobble in Earth’s axis of rotation), nutation (a slight wiggle in the tilt of Earth’s axis), and the gradual drift of Earth’s elliptical orbit.

Our star maps do not account for the movement of individual stars through space, relative to each other, known as proper motion. This movement is typically so slow as to be minimal over centuries, but the positions of some of the stars in the Northern sky during the last ice age may be in slightly different locations than shown.

In our visualizations, we used the familiar names Scorpio and Capricorn instead of the official names for those constellations: Scorpius and Capricornus. The seasons we describe are for the Northern hemisphere. The Earth’s orbit around the sun is actually counterclockwise when viewed from above; we show it orbiting clockwise for illustrative purposes. The Earth and the sun are not to scale.

A secret-ish Japanese-style listening lounge just opened inside the Hollywood Palladium

Now you can pair your big show with dinner and a more intimate listening experience. The Hollywood Palladium, an Art Deco music venue graced by performers like Frank Sinatra, Richard Pryor, Jimi Hendrix, Lady Gaga and Jay-Z since 1940, has debuted a swanky lounge known as Vinyl Room.

Inspired by 1970s Japanese high-fidelity (hi-fi for short) listening rooms and operated by entertainment company Live Nation, it’s a space where concertgoers can have dinner, grab drinks and catch a vinyl DJ set before, during or after their ticketed event in the same venue.

With a name like Vinyl Room, you can expect to see vinyl records everywhere.

“You’re in [for] a whole night of music,” says Geni Lincoln, president of the California region for Live Nation, adding that her team put “so much thought” into the sound and design of the space, which was in development for more than two years.

“I’ve been coming to the Palladium since I was a teenager, so it’s really special to see,” she says.

Entering Vinyl Room feels like you’re stepping into a secret speakeasy for music lovers, one with iconic music memorabilia, a thoughtful food menu and premium sound quality. Want to check it out? Here are five things to know.

Two people play cards at Vinyl Room.

Everything inside of Vinyl Room is inspired by the sounds and the musicians who’ve played at the Hollywood Palladium since 1940.

1. Vinyl Room is exclusively open to members and concertgoers with an upgraded ticket

Vinyl Room is open only on Hollywood Palladium show nights, starting 90 minutes before doors open, and remains open one hour after the concert. Admission is limited to concertgoers who purchase a ticket upgrade, which starts at $35. Early reservations are recommended.

Vinyl Room also offers annual membership packages, which start at $2,000 and come with various benefits such as complimentary guest passes to Vinyl Room, access to an exclusive menu, valet parking, table reservations inside the lounge, a dedicated private entry, complimentary coat check and concert ticket credits.

2. Hi-fi is having a moment in Los Angeles — and Vinyl Room delivers on sound quality

From Common Wave Hi-Fi in Boyle Heights to Slow Jamz Gallery in the Arts District and Gold Line bar in Highland Park, hi-fi — a 1950s term used to describe the high-quality reproduction of sound — venues and experiences have been slowly popping up around L.A. over the last few years. Vinyl Room joins a short list of places where audiophiles can go to listen to music on hi-fi equipment, which many argue is the best way to experience it.

Much like the Hollywood Palladium, which is known for its top-tier sound, Vinyl Room also makes sound a priority. The lounge utilizes hi-fi sound equipment including Master Sounds Clarity-M speakers to ensure that the records sound as crisp as possible. Live DJs spin records on a set of turntables, which helps to create a richer and more analog sound that is closer to the original track than compressed versions such as MP3s.

Vintage concert posters decorate the walls at Vinyl Room.

Ruthie Embry, vice president of architecture and design at Live Nation, says the records and other memorabilia inside the space “connects you directly to the venue’s history the second you walk in the door.”

3. All of the decor ties back to music and the Hollywood Palladium’s rich history

With a name like Vinyl Room, you can expect to see vinyls everywhere. Records line most of the walls and shelves, drinks are served on vinyl-shaped coasters and tables and light fixtures are designed to the theme. There’s even vinyl wallpaper in the photo booth. In one corner of the lounge, you can dig through records under a neon sign that reads, “But have you heard it on vinyl?”

Ruthie Embry, vice president of architecture and design at Live Nation, says the records and other memorabilia inside the space “connects you directly to the venue’s history the second you walk in the door.”

Some standout items include a Red Hot Chili Peppers show flier, a Hollywood Palladium postcard signed by late musician and host Lawrence Welk and a photo of late singers Bonnie Baker and Orrin Tucker at the venue. Even the bathroom creates a memorable photo moment: The stalls are filled with photos of musicians and an “on air” studio sign lights up when a stall is occupied.

Food served at Vinyl Room in Hollywood.

Vinyl Room’s menu, created by Chef Ryan DeRieux, is inspired by Asian flavors and includes items like the “Vinyl Roll,” which is made with spicy tuna.

4. Don’t worry about dinner plans before or after the show. Vinyl Room has got you covered

Eliminating the need to find a pre- or post-show restaurant, Vinyl Room has a full Asian-inspired menu created by Chef Ryan DeRieux.

Think sushi tots (like crispy tuna but with tater tots instead of rice), tuna poke nachos, chili crunch chicken wings and shiitake tempura burgers. There’s also a mouth-watering 10-ounce American wagyu skirt steak served with shishito peppers, pickles and charred carrots. For dessert, try the taiyaki, a popular fish-shaped Japanese street food, which is served with a delicious passion fruit cream that I wanted to take to go because I liked it so much.

Cocktails at Vinyl Room

Signature cocktails at Vinyl Room, inspired by popular songs, include the Superfly, Escape (if you like piña coladas) and Smoke on the Water.

5. The craft cocktails aren’t just delicious — they each have a story

Vinyl Room's old-fashioned is made with Nikka Yoichi whisky, which is made in Japan.

The cocktail program, developed by third-generation bartender Sean Kenyon, is inspired by the songs created by musicians who’ve graced the Hollywood Palladium stage. A nod to the 1970s, the Superfly is a fizzy, citrus-forward play on Curtis Mayfield’s 1972 track and is made with Roku Gin and yuzu and sencha syrup. Other signature drinks include the rum-based Escape (if you like piña coladas) with coconut oolong syrup, pineapple juice and miso, and the tart yet sweet Smoke on the Water, which is reminiscent of Deep Purple’s 1972 song. The bar also offers an espresso martini (called the MT Joy), a signature old-fashioned (made with Nikka Yoichi whisky) and a Japanese whiskey highball (made with Hibiki Harmony whisky). The bar offers a number of non-alcoholic options as well.

Found: The 19th century silent film that first captured a robot attack

A screenshot from George Mélière’s Gugusse et l’Automate. The pioneering French filmmaker’s 1897 short, which likely features the first known depiction of a robot on film, was thought lost until it was found among a box of old reels that had belonged to a family in Michigan and restored by the Library of Congress.

The Frisbee Collection/Library of Congress

The Library of Congress has found and restored a long-lost silent film by Georges Méliès.

The famed 19th century French filmmaker is best known for his groundbreaking 1902 science fiction adventure masterpiece Le Voyage dans la Lune (A Trip to the Moon).

The 45-second-long, one-reel short Gugusse et l’AutomateGugusse and the Automaton – was made nearly 130 years ago. But the subject matter still feels timely. The film, which can be viewed on the Library of Congress’ website, depicts a child-sized robot clown who grows to the size of an adult and then attacks a human clown with a stick. The human then decimates the machine with a hammer.

In an Instagram post, Library of Congress moving image curator Jason Evans Groth said the film represents, “probably the first instance of a robot ever captured in a moving image.” (The word “robot” didn’t appear until 1921, when Czech dramatist Karel Čapek coined it in his science fiction play R.U.R..)

“Today, many of us are worried about AI and robots,” said archivist and filmmaker Rick Prelinger, in an email to NPR. “Well, people were thinking about robots in 1897. Very little is new.”

A long journey

Groth said the film arrived in a box last September from a donor in Michigan, Bill McFarland. “Bill’s great grandfather, William Frisbee, was a person who loved technology,” Groth said. “And in the late 19th century, must have bought a projector and a bunch of films and decided to drive them around in his buggy to share them with folks in Pennsylvania, Ohio, New York.”

McFarland didn’t know what was on the 10 rusty reels he dropped off at the Library of Congress’ National Audio-Visual Conservation Center in Culpeper, Va. A Library article about the discovery describes the battered, pre-World War I artifacts as having been, “shuttled around from basements to barns to garages,” and that they, “could no longer be safely run through a projector,” owing to their delicate condition. “The nitrate film stock had crumbled to bits on some; other strips were stuck together,” the article said. It was a lab technician in Michigan who suggested McFarland contact the Library of Congress.

“The moment we set our eyes on this box of film, we knew it was something special,” said George Willeman, who heads up the Library’s nitrate film vault, in the article.

Willeman’s team carefully inspected the trove of footage, which also contained another well-known Méliès film, Nouvelles Luttes extravagantes (The Fat and Lean Wrestling Match) and parts of The Burning Stable, an early Thomas Edison work. With the help of an external expert, they identified the reel as having been created by Méliès because it features a star painted on a pedestal in the center of the screen – the logo for Méliès Star Film Company.

A pioneering filmmaker

Méliès was one of the great pioneers of cinema. The scene in which a rocket lands playfully in the eye of Méliès’ anthropomorphic moon in Le Voyage dans la Lune is one of the most famous moments in cinematic history. And he helped to popularize such special effects as multiple exposures and time-lapse photography.

This moment from George Méliès' Le Voyage dans la Lune (A Trip to the Moon) is considered to be one of the most famous in cinematic history.

Presumed lost until the Library of Congress’s discovery, Gugusse et L’Automate loomed large in the imaginations of science fiction and early cinema buffs for more than a century. In their 1977 book Things to Come: An Illustrated History of the Science Fiction Film, authors Douglas Menville and R. Reginald described Gugusse as possibly being, “the first true SF [science fiction] film.”

“While it may seem that no more discoveries remain to be made, that’s not the case,” said Prelinger of the work’s reappearance. “Here’s a genuine discovery from the early days of film that no one anticipated.”
